STM32H7 Ethernet Connection Lost

[Kuttay]

I am using open source lwip ethernet connection code and I am cehcking wireshark if i lose any connection. TCP ECHO parts are my true outputs but i was wondering if ARP parts means that my connection is lost and I reconnect or is it just checking gateway only. I try to stable my connection and dont want to disconnect. So what does arp broadcasts really means in that situation?Wireshark Test ss

Hello @Kuttay ,

In this case it seems that the ARP request is sent by your computer (dell mac source address) looking for 192.168.0.0 which is not responding and don't have any effect on the board connection and TCP echo function between the board and PC.
